1,3,7-triazapyrene-based ortho-carborane fluorophores: convenient synthesis, theoretical studies, and aggregation-induced emission properties / L. A. Smyshliaeva, M. V. Varaksin, E. I. Fomina [et al.] // Organometallics. - 2021. - Vol. 40, № 16. - P2792-2807 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A convenient transition-metal-free approach, based on nucleophilic substitution of hydrogen (SNH), for consecutive regioselective C–H functionalization of 1,3,7-triazapyrene scaffolds with carboranyllithium and phenyllithium is reported. The theoretical calculations disclosed highlight key features in the regioselectivity and mechanism of the investigated SNH transformations. The novel 1,3,7-triazapyrene-based ortho-carboranes obtained have large potential in the field of molecular electronics as organic luminophores, which are characterized by the aggregation-induced emission and dual-emission effects. |
